OFFICE HUGH COOKIE ARMSTRONG, OF COLUMBUS, OHIO, ASSIGNOR OF ONE-FOURTH '.I'.O WILLIAM M. GINDEB, OF COLUMBUS, OHIO ROLLING DOOR WITH GLASS-COVERED OPENING Application filed March 9, 1931, Serial No. 521,264, and in Canada March 9, 1931.

My invention relates to rolling doors and in particular to an apparatus and method of operation of an apparatus for placing windows in fireproof rolling steel doors.

It is the object of my invention to provide a rolling steel door of articulated slat-s in which are mounted when the door is in closed position, permanently fixed fireproof windows covering openings in the articulated slats so that the door will have such openings closed by the frames and glass of the windows but will permit full vision through the door.

It is a further object of my invention to provide any number of windows and window sash transversely or in superimposed relationship so that any part or substantially all of the door opening may be seen through according to the number of windows provided. and light is admitted.

It. is a further object to provide means of storing the window sash and windows within the compass of the dimensions of the door in a protected place where they will not be injured when the door is in open position and the windows are inoperative.

It is a further object to provide means of counter-balancing such windows independently of the rolling door and the counterbalancing mechanism of the rolling door while at the same time utilizing the rolling door for actuating the windows in cooperation with their counter-balancing mechanism and the counter-balancing mechanism of the door itself.

Referring to the drawings, Figure 1 is a front elevation of the door in closed position with the door counter-balancing mechanism partly broken away showing a single sash installed in parallel relationship to cover a pair of openings in the articulated door.

Figure 2 is a section on the line 22 thereof.

Figure 18 is a view similar to Figure 16 showing the sash attached to pulleys, cables and weights for counter-balancing.

Figure 19 is a section on the line 19-19 of Figure 18.

Referring to the drawings in detail, 1 indicates the structure of the building, a door opening which is closed by the rolling door comprising the articulated slats 2 that are interlocked to form hinges as at 3.

The bottom of the door is provided with a transverse stri 4 riveted to the lower articulated slat 2. n this lower bar 4 is mounted a plate 5. Riveted to the slat 2, bar 4 and plate 5 at either end thereof are semi-circular members 6 which form guide bearings engaging the inner walls of the channel guide '7 ticulated slats 2 is wound upon the drum 11,

to which the articulated door curtain 2 is at- .tached at 12. Suitable counterbalancing mechanism may be mounted within the cylinder 13, but the nature of the counter-balancing mechanism, of which there are various forms in the art, is not important in this invention. The curtain is actuated through the hand chain 14 engaging the sprocket wheel 15 which carries the pinion 16 that meshes with the gear 17. Upon the actuation of the chain in conjunction with the counter-balancingdmechanism, the door is raised and lowere This door is provided with window openings 18. The window openings are formed by cutting a portion of the slats 2 as at 19 into short sections and placing on either end of these short sections retaining plates consisting of an attaching plate 20 to the face of the slat with a vertical retaining face 21 extending over the joints 3 of the adjacent slats, thereby preventing lateral movement between the adjacent slats 19. Similar slats are mounted on the ends of the full length slats -2. Thus the articulated door curtain forms window openings.

On the back of the curtain adjacent the openings is mounted a diagonal clamp 22 riveted to one of the slats 2 of the rivet 23, which also passes through a front reenforcing plate 24.

The clamp and plate has a diagonal portion 25 for overlapping a similar diagonal clamp member 26 which is mounted upon the lower part of the window sash 27 When the structure is in closed position this window sash 27 rests upon the bracket 28 mounted within the window sash guide frames 29 on either side of the door opening.

The window sash 27 carries a window frame 30 in which is mounted wire glass 31. As the rolling door and steel window frame sash and wire glass are all fireproof, a tight fireproof construction isprovided for closing the door opening.

The sash may be connected at its upper corners to suitable cables 32 passing over pulleys 33. Such cables may be-connected to independent springs for counter-balancing purposes such as at 34 in Figures 14 and 15, or the cables may be wound on the pulleys 33 which in turn are mounted on the spring actuated drum 35 which in turn is actuated by the spring 36 as in Figures 16 and 17. The spring 36 is connected at 37 to the drum 35 and to a stationary abutment 38 at its other end. Again, the cables 32 passing over the pulleys 33 may be attached to counterbalancing Weights 39 as in Figures 18 and 19.

As will be seen from Figure 8, when the door starts upwardly, the flange 9 on the bottom of the rolling door will engage the bottom of the sash 27 and impart to the sash such movement in conjunction with its counter-balancing mechanism to move it upwardly with the rolling door. During this upward movement the sash is guided in its own track 29 that is parallel to the track 7 which guides the rolling door. The track 29 extends vertically against the wall above the door opening indicated at 40. The sash is thus stored telescopically behind the winding mechanism for the door and within the casing 41 that encases the door actuating mechanism.

No greater heighth is necessary for the total door mechanism as the sash is stored behind the door operating mechanism.

In the event it is desired to use multiple sash or sash of greater depth, all that is necessary is to extend the casing for the sash upwardly, in the event there is sufficient. room between the top of the sash when in their uppermost position and the ceiling of the room.

Double sash When it is desired to use a plurality of superimposed sash, as shown in Figures 11, 12 and 13, the sash are duplicates of one another as heretofore described, there being provided for the upper and second sash which is superimposed, the first or lower sash already described, an additional guideway 42 for the sash 43 carrying its window frame 44 and glass 45. Mounted upon the first mentioned sash 27 is a lifting plate 28 that serves to engage the bottom of the sash 47 when the lower sash is elevated by the lifting plate 9 on the bottom of the rolling door. It will be understood that any number of sash may be employed by this system,' telescopically arranged one behind the preferably within the casing 41. w

Similar counter-balancing mechanism may be provided for this sash as indicated in Figures 14 to 19 inclusive.

th r a Extension of sash across the door curtain door but the sash extend completely across the curtain and into the guides for the sash. The sash are provided with end plates 48 and center plates 49 which may be of any width to fill in the spaces between the windows. While this is not essential, yet it provides reenforcement for the window sash.

I desire to comprehend within my invention such modifications as may be clearly embraced within my claim and the scope of my invention.
